推荐答案
这与 这个问题.
LINQ to SQL 将在需要时打开和关闭连接 - 您实际上不必处理 DataContext.但是，有时您可以欺骗"上下文以在您不应该打开连接时保持打开状态 - 我个人喜欢将其作为理所当然的处理.有关 LINQ to SQL 团队的 Matt Warren 的更多详细信息，请参阅我对另一个问题的回答.
LINQ to SQL will open and close connections when it needs to - you don't really have to dispose of the DataContext. However, there are times when you can "trick" the context into leaving a connection open when you shouldn't - I personally like to dispose of it as a matter of course. See my answer to the other question for a bit more detail from Matt Warren of the LINQ to SQL team.
不过，我不了解实体框架.
I don't know about the Entity Framework, however.
